– Murderess

Murderess (Japanese: マードレス, Mādoresu; English dub: /ˈmɜːrdərᵻs/ or /ˌmɜːrdərˈɛs/), originally Sharon Effinger (Japanese: シャロン・B・エフィンジャー, Sharon B Efinjā; English dub: /ˈʃærən ˈɛfᵻndʒər/ or /ˈɛfɪŋdʒər/), is a recruitable playable character in Xenoblade Chronicles X. She is a Curator and a member of the private military organization BLADE.


Murderess is a human with pale skin, white-blonde hair in a bob-cut with blunt bangs, and purple eyes. She is of average height and build.


Murderess first appears to be a very selfish and greedy individual who will stop at nothing to gain more wealth. She has gained a reputation for double crossing her fellow BLADE members just to claim the entirety of a mission's reward for herself, and often manipulates other BLADE members into doing her bidding. She also tends to draw the ire of Irina, though the two later reconcile and become friends. She is revealed to be Sharon Effinger, a girl from a rich family whose parents were slain when she was young. She discloses that her ultimate goal is to restore the Effinger name on Mira and honor her murdered parents. Though she does not actually kill anyone, she uses the alias "Murderess" to remind herself that she would someday avenge her parents.

Main story

Mardreth in Skell

Murderess piloting a Skell

Murderess has a minor appearance during the course of the main story. First, she is seen in her Skell in Chapter 12 when all BLADEs are commanded to defend Elma's team once they are inside the Lifehold Core. Murderess also appears in the ending credits scene, where she is seen interrupting and provoking Irina on her lunch date with Gwin.

Personal story

Mardreth the Betrayer

Murderess betraying the party

Murderess' full story is divulged in the Affinity Mission Serial Thriller, in which Murderess is accused of a string of recent murders in New Los Angeles, including acquaintances of hers, such as Yolanda and Otis. She later connects the killings to Dale Gibbon, the man who murdered her parents in cold-blood when she was young, due to him killing the NLA victims in the same way that he cut down her parents. She and the party confront him in Sylvalum, posing under the name Martin, where he admits to his past and says that he is been fantasizing of killing the last of the Effingers since he saw her on Mira. It is here that Murderess discloses why she took on the name "Murderess", saying that she did it to stay strong, to remind herself that she would someday get vengeance. She then says that she no longer feels that she needs to kill him, especially since she herself is not a murderer, and will not go by the name Sharon Effinger again until she achieves her dream of restoring the Effinger name on Mira. She and the party then depart for NLA and leave the injured Dale Gibbon to his fate, where he is swiftly approached and killed by an indigen. In the aftermath, Murderess and Irina have developed a new respect for each other, and their affinity link changes to friendship.

Default "Ah, Cross. Pleasure. I was just thinking about how I'd enjoy working with a big strong BLADE like yourself again. No, no! I mean it. You really should take me along." "Wonderful. Oh and relax. I promise not to shoot you in the back or anything." "Well, that's a bummer. And here I thought I might actually get a decent payday for once."
Chapter 7 "So Little Miss Sweetness is in trouble, eh? Well, I'm certainly no fan of people being killed by the Ganglion, so if you're going to save her, I'll chip in." "Let's get going. I'll never be able to cash in on favors from her if she dies." "Well, that's a shame. I thought it would be an easy way to put her in my debt."
Chapter 9 "If you're going to Sylvalum, there's a good chance you might find some undiscovered treasures. Hmm... You know, if you need a hand, I suppose I'd be willing to accompany you." "Perfect! Oh, and I hope you understand that if I'm going to such a dangerous place, I'll need a reward commensurate with my efforts." "My, aren't we cocky! Well, I'll overlook it this once."
Chapter 10 "How's that? You received another mission straight from Vandham? My my my, aren't we a big shot? I don't know what it entails, but I'm sure Vandham rewards you well for these sweetheart deals of his. So count me IN!" "Heh heh heh. If I complete this mission, I'll demand Vandham put me on the sweetheart job track too!" "Shame. We'd have made such a lucrative team."
Chapter 11 "Who knows what a man like that is thinking? Or what he'll do next? He needs to be removed from the picture before he can do something else foolish." "Nice. I'll go sharpen my killin' blade." "Without me, is Team Goody Two-shoes really equipped to do what needs to be done to that man?"
Chapter 12 "No matter how much money you hoard, you still need to be alive to spend it. So it's imperative that we complete this mission. ...That's WE. Not you and someone else. We." "Does finding the Lifehold Core take us closer to heaven or hell? I can't wait to find out!" "Hmm. Well then, good luck. Oh, and make sure you succeed, okay? Because if you don't... ...I'll find you in hell and kill you again. Ta-ta!"
